Structure - an arrangement of parts

Solid Structures

Coral – Coral is a structure built by millions of organisms. It is essentially a solid structure with no space enclosed by the material from which it is built.

Stone fence – These stones are arranged into a structure that serves the function of defining a property line and setting up a barrier. The wall is solid, and it is the weight of the stones themselves that provide strength and stability to the wall.

Solid Structures

Fanshawe Dam – A dam is basically a solid mass structure. Although there may be a small control room enclosed inside, the walls are very thick in proportion to the space inside.

Statue – The statue is made from material poured into a mold and is solid.

Frame Structures

Skeleton – The skeleton of any animal provides support for the body. The skin provides a cover, but it is the bones of the skeleton that support the weight of the animal.

New house – In this house under construction, the wooden framework is clearly visible. It rests on a cement block foundation. Drywall will be attached to the framing to enclose spaces. The wall joists and roof trusses support all of the weight of the building.

Frame Structures

Soccer net – The soccer net is a simple frame structure.

Hydro tower – The steel framework of the Hydro tower supports the weight of the structure.

Skyscraper – Reinforced concrete beams and columns provide the structure of the skyscrapers. The weight of the outer shell of concrete and glass hangs on this framework.

Shell Structures

Lobster – The shell of the lobster is made of a hard, rigid material containing calcium. For any animal that has an exoskeleton, it is the outer shell that supports the animal.

This stove has a shell of sheet metal.

Water tower – The sphere at the top of the water tower does not contain an internal framework.

Shell Structures

Victoria Park Bandshell – Most of the weight of the structure is found in the shell.

Aquatic Centre – The corrugated steel shell is very rigid and creates a structure which contains a large open space.

Computer case – The rigid plastic/metal of the case of this computer is sufficiently strong to protect the internal parts.
